SEALING-HEAD FOR BOTTLE-SEALING MACHINES.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed May 2'7. 1907. Serial No. 376.086.

L '0 all whom it may concern.

' Be it known that I, EDWARD D. Semn'r'r, citizenof the United States, residing at Brooklyn, in the county of Kings and State ol'New York, have invented certain new and useful. Im rovements in Sealing-Heads for Bottle Sea ing Machines, of which the following is a specification.

This invention relates to improvements in sealing heads for use in applying hard metal flanged caps to a bottle having a locking surface or shoulder adjacent to its mouth.

' l't will be understood that the head about .to be described may be employed with any suitable means for depressing it, or in con n'ection with any suitable bottle support or means for raising said support to get the desired sealing pressure.

In the drawings :Figure 1 is a central sectional view of the head with a bottle seal therein in dotted lines; Fig. 2 is a similar view, showing the parts about in the position they assume at the time of locking the flange of the seal, the upper end of a bottle having a cap thereon being shown in section; Fig. 3 is a cross section about on line; aa Fig. 1.

The numeral 1 designates the head casing which is generally cylindrical in form and comprises in the main,'thc up )cr section 2 and the lower section 3. The lower section is enlarged to receive and accommodate the locking mechanism and the lower part of the plunger. In order that the parts may be conveniently assembled, I attach the lower part of the casing to the upper part by means of threads 4, and the upper end of the casing is internally threaded as indicated at 5 for the reception of the screw cap 6.

The plunger is composed of two independently movable parts, which at some time have a movement in common, but the movement of one part is arrested or retarded at the mint where it is desiredto actuate the seal locking devices.

The numeral 7 designates the lower plunger part and the numeral 8' designates the upper .art. The plunger stem 9 carries at its ower end a head 10 that fits snu ly within the bore 11 of the lower part of t e casing. The head 10 is provided with a cavity 12, and the upward movement of the seal therein in placing it in thehead is limited by a head 13 having a shank 14 threaded into the stem 9. The adjustment of this head 13 serves to vary the sealing pressure of the plunger, or

the point at which the re uired or' desired sealing pressure is" applie to the seal and bottle. The head 10 is provided with a'plurality of radial recesses preferably six" in number, in which are pivoted levers 15. The lower ends of these levers present'ind n't ing noses or points 16, which are adarteo to be projected at proper times simultaneously into the seal cavity. The upper arms of the levers are perforated 'as indicated at 16 for the passage of, the lower ends of rods 17, which are threaded as indicated at 18" near their upper ends by which means they are firmly held in the upper plunger part 8. These rods are surrounded by spiral springs 19 whose upper ends engage the under face of the part 8 with their lower ends resting upon the arms 16 ofthe levers 15. The upper plunger part 8 has'a central reduced portion 20 that extends slightly into the bore 21 of the upper art of the casing. The upper end of the p unger stem 9 is provided with a cross head 22, upon which rests the lower end of the sealing spring 23, the upper end of said sealing spring being in enga ement with the screw cap 6. Against t is spring the lower part of the plunger moves upwardly or yieldingly in the sealing 0peration.

The downward movement of the lower plunger part is limited by .a ledge 24 formed on the lower part of the casing. The upper plunger part 8 rests normally upon a shoulder 25 in the lower part of the casing, and a s ace 26 is left between the up er surface 0' the upper casing part, to allow for thenecessar movement upward of the part 8 in the seaing operation.

In operation, a cap is placed in the seal" holding cavity where it may be held temporarily by the ends 27 of spring backed olding pins 28, or by friction, or in fact, by any suitable means. When the head is lowered or the bottle raised, the lower plunger part will, in the initial movement, move upward against the influence of the spring 23. The plunger part 8, by reason of the yioldin connection between the locking levers and said part, in the way of the springs 19, will also e moved upwardly, until the up er surface of the part 8 engages the. lower edge of the upper part of the casing, when further '90 plunger part 8 and the ower edge of theupward movement of this part wilbbe" re' desired to lock the seal upon the bottle and a slight further upward movement of the lower part of the plunger against the influence of the spring 23, will cause the locking levers to be rocked, through the rod, and spring connection, yieldingly into engag'e ment with the flange of the seal, indentin it at intervals under the locking shoulder. y reason of the yielding movement of the the application of the seal, is eliminated. The tension of the springs 19 in-the final locking movements is considerable, suflicient erly indent and lock the seal.

tion may be made within the spirit of this invention, and while I have described the sealing head as especially adapted for applyl ing'hard metal flanged caps to bottles having 20 an annular locking surface or shoulder adjacent to their mouths, it will be understood that the heads would be equally adapted for appl ing ca 5 or covers to vessels other than bott es, sue as glass jars, cans, etc., it being sions of the head parts to accommodate them to such additional uses.
